How LATAM Airlines Check-In Works and What to Expect

If you’re flying with LATAM Airlines, understanding how the LATAM check-in process works can really help you start your trip on the right note and avoid any last-minute stress. LATAM is the largest airline group in South America (and one of the largest globally by passengers transported), with strong domestic operations in Brazil, Chile, Colombia, Ecuador, and Peru. It connects internationally across South America and to/from North America, Europe, Oceania, and Africa, serving around 150-170 destinations in about 28-31 countries (numbers vary slightly by source, including codeshares and cargo-exclusive). In 2025, LATAM transported 87.4 million passengers. The group operates a fleet of more than 350 aircraft (including dedicated cargo freighters), primarily modern Airbus and Boeing models, with ongoing modernization and a strong emphasis on efficiency and sustainability.

Understanding LATAM Check-in Basics

LATAM check-in is the step where you confirm your flight details, choose your seat if it’s available, and get your boarding pass. The airline keeps this process simple and quick, especially with its focus on digital options. For most flights, LATAM check-in opens 48 hours before departure, allowing time to confirm details, select seats (if available), and obtain your boarding pass. This process also ensures travel documents are verified (especially for international flights), and baggage is handled properly.

One helpful thing to know is that LATAM offers automatic check-in for many domestic flights, which saves you the trouble of doing it yourself. Just keep in mind that check-in rules can change depending on your route, whether you’re flying within South America or heading to places like Europe or the United States. That’s why it’s always a good idea to double-check your specific flight details before travelling.

Methods of LATAM Airline Check-in

You can complete your LATAM airline check-in in a few easy ways, so choose what works best for you.

Automatic Check-in for a Smooth Start

If you booked a domestic flight with Flightsquest or directly on the official website or app and the flight is operated by LATAM, you may be eligible for automatic check-in. This option starts 48 hours before departure and completes the check-in for you. Your boarding pass will then show up in the “My Trips” section on the website or mobile app.

To access it, just log in using your booking code and last name. LATAM Pass members can sign in with their membership number and password for faster access. Get your boarding pass by downloading it or printing it out. If you have checked baggage, use a self-service kiosk at the airport to tag your bags and drop them at the counter.

This option works best for solo travelers or small groups on simple domestic routes. Keep in mind, it doesn’t apply to international flights or tickets booked through travel agencies.

Check weight limits and avoid extra charges by reviewing the LATAM Airlines baggage policy before packing.

LATAM Airlines Check-in Online and Web Check-in

If you’ve booked your flight with Flightsquest, you can have more control over the LATAM Airlines check-in online through the Flightsquest website or the app. Start by visiting the Flightsquest website and clicking on “My Trips” or “Check-in.” You’ll need:

• Your booking reference (a six-character code)

• Your last name

You can also sign in using other options, like:

• Your LATAM Pass membership number and password

• Frequent flyer details from a linked partner program

• A direct link sent in your booking confirmation email

Once logged in, you can:

• Enter passenger details, including passport information for international flights

The LATAM Airlines web check-in usually opens 48 hours before departure and closes about 3 hours before the flight.

Track departures and arrivals in real time using LATAM Airlines flight status tools before heading to the airport.

Airport Check-in Options

If online check-in isn’t for you or you need extra help, you can complete your LATAM check-in at the airport at the counters or self-service kiosks (for boarding pass printing and bag tagging).

Recommended arrival times at the airport:

• Domestic flights: At least 2 hours before departure (exceptions may require 3 hours at certain airports, e.g., in Peru, like Lima—check your specific origin).

• International flights: At least 3 hours before departure (up to 4 hours at specific airports, e.g., Caracas, due to local regulations—verify for your route). Use kiosks for quick boarding pass and baggage tag printing. For groups, special assistance, bulky items, or baggage questions, speak directly with LATAM staff at the counter.

Special Considerations for LATAM Airlines Group Check-in

If you’re traveling with a group, the LATAM Airlines group check-in process is easier, especially for large or corporate bookings. When a trip is booked through the corporate portal, check-in and seat assignments are often handled in advance by a dedicated team. You can access the booking using the group reference on the website.

For regular group bookings, online check-in is still available, but it’s usually done individually or in small batches. At major airports, you may get dedicated LATAM Airlines group check-in counters. If you’re managing several passengers and want everyone seated together, it’s a good idea to contact LATAM’s support team for help.
